Problems solved by technology

[0019] The defect of the existing dual-star switching interconnection is that for a specific data channel connection, the switching board only supports one switching plane. In practical applications, the switching capacity of the switching plane cannot be adjusted according to the change of the data bandwidth of the node board. flexible configuration
[0025] The defect of the double-star switching interconnection is that although the dual-star switching interconnection topology uses two dual-star switching structures, the communication bandwidth between the node boards is doubled, but the two switching structures are independent
Similarly, in the existing multi-switching plane mode, one switching board only provides one switching plane, and it is difficult to realize the flexible configuration of the switching capacity of the ATCA system

Embodiment 1

[0059] Example 1: Divide 4 switch ports into 4 groups

[0060] (1) The switching ports all use the same switching protocol

[0061] Figure 8 It is the switch interconnection configuration diagram of 2 switch boards and N node boards (N is less than or equal to 14) in the first embodiment (CxPy means "channel x port y"). The following describes the 4 ports of each channel of the switch board It is divided into 4 groups, and how to achieve linear expansion of switching capacity in the case of sending and receiving differential signals in each group.

[0062] The ATCA system adopts the multi-plane switching mode. The input stage and output stage of the multi-plane switching are located on the node board, and the intermediate stage is located on the AMC of the switching board. Each input stage has 8 pairs of sending and receiving differential signals, of which 4 pairs of sending and receiving differential signals are connected to 4 AMCs of switch board A (represented as AMC1, A...

Embodiment 2

[0068] Example 2: Divide 4 switch ports into 2 groups

[0069] (1) The switching ports all use the same switching protocol

[0070] When the system is implemented, the 4 ports of each channel of the switch board can also be divided into 2 groups, and each group has two pairs of differential signals for sending and receiving, and a maximum of 4 switching planes can be configured. At this time, each switch board has two AMCs, and each AMC is a switching plane, such as Figure 9 shown.

[0071]The ATCA system adopts the multi-plane switching mode. The input stage and output stage of the multi-plane switching are located on the node board, and the intermediate stage is located on the AMC of the switching board. Each input stage has 8 pairs of sending and receiving differential signals, of which 4 pairs of sending and receiving differential signals are connected to the two AMCs (denoted as AMC1 and AMC2) of switch board A, and 4 pairs of sending and receiving differential signals...

Embodiment 3

[0082] The configuration system of the switching network of Embodiment 3 of the present invention is an ATCA system, which includes a plurality of node boards, two switching boards and a plurality of AMC modules; each switching board is adjustably provided with 1 or more than 1 AMC modules, Each AMC module serves as a switching plane; the node board includes an input stage and an output stage of a switching network, and the switching plane of the switching board is provided with an intermediate stage of a switching network.

[0083] In the case of two switch board configurations, if four AMC modules are configured on one switch board, that is, four switching planes, each switching plane and node board can be interconnected through one port; If two switching planes are configured, each switching plane and the node board can be interconnected through two ports; if one switching plane is configured on one switch board, the switching plane and the node board can be interconnected t...

Abstract

The invention provides a configuring method and a system for an exchange network, which adopts the multi-plane exchange method in the communication system by arranging the input level and the output level on the node board; wherein, at least two exchange boards are arranged, with the medium level arranged on the exchange module of the exchange board, taking every exchange mode on the exchange board as a exchange plane; the number of exchange planes are configured by means of controlling the number of exchange modules inserted on each exchange board. The invention can flexibly configure the exchange planes of the exchange network according to the actual bandwidth needs of the node board so as to linearly extend the exchange bandwidth.
